Nice article thanks.

There is something that maybe you should have mentioned here. The fact the same side of the moon always faces us, due to it being "tidally locked" with the Earth.

Another way to think of this is that the moon spins on its axis at the same rate that it makes a complete orbit of the earth. So the two motions "cancel" each other and results in the same face of the moon always facing Earth.

I thought i'd add this because it's an important aspect involving the phases of the moon.

I hope that contributed.
